The Lobo scope made by T/C was similar or even the same as the Bushnell rail mount handgun scope. You probably have Loc-Tite under your rail mount base which isn't uncommon and no, DON'T throw that base away. T/C made quality 1" tube rail mount scopes that are compatable with that base and you're thrownig away $10 at least. The lobo scope is a much smaller tube and gathers little light. The lenses are pretty poor and it was a low end scope to begin with so no, it's no prize. Depending on the caliber, you might be served well by the scope but there are definately better ones out there.
